FIMPROVEMENT l N STEAM-TRAPS.

Specification forming part of Leilers Patent No. 47,304, dated April 1&{18 5.

To all whom it may concern Be it known that 1, PETER Head, of the cit 3', county, and State of New York, have invented a new and Improved Steam-Trap and I do hereby declare that the following is a full, clear, and exact description or the same, rei

erence being bad to the accompanying drawcircumstances, and-of the utmost simplicity in its construction.

The water of condensation is received in a "tight metallic casing, through the bottom of which is passed a pipe closed at its top and, perforated with a series 'of lioles at a small distance above the bottom of the casing. An open vessel in shape-like an ordinarypail,

but having a collar fitted around and extendin g a short distance above an openin g through the center of its bottom, fits over the pipe, and its collar acts as a movable valve-seat to j the perforations in the pipe. This collar or valve-seat covers the holes when the float is at rest and-uncovers them when it is in mo tion, so as to discharge the water.-- When the pressure of thewater in the casing raises the floating pail, it uncoversthe lower" holes in the discharge-pipe,so' as to discharge the water from the casing, and when water has accumulated in the" pail so as to carry'its collar oryalyegseat below the upper holes of the pipe, theii'this water is also emptied into the pipe andthe float is restored to its place so as i it will'close all the holes in the pipe.

To enable those who are sk'lled in this branch of mechanics to understand and construct my invention, I will proceed to describe it more fully.

A is a metallic casing, within which the other parts of the trap are inclosed. Mhen the trap isready for use, this casing is to be closed steam and water tight; A pipe, G, is here shown connecting the trap with the steam-pipes or other apparatus whichare to be cleared'of the Water of condensatiomthe' pipe e'ntering'the casing at or near a point, 9, or at any other point on its sides or on its top. The trap may receive water of condensation from more than one sourcefby means of addi tional pipes, and the p'iiie or pipes, which, as indicated in red outline, enter-the trap through its top, will discharge themselves into the open pail beneath. The pipe D, which is closed at top,passes through the bottom of the casing and is supported by itsflangenwhich rests upon the bottom of the casing and is secured in position bythe nut 1}, working on a scrcwthread on the pipe and turned up snugly against the under side-of the casing, thus clamping it between the flangeof the pipe and the nut. An open vessel or pail, B, is

fitted around thepipe Dby means ofv a hole through its bottom, A guide-piece, O,'acrossthe mouthof the pail through which the pipe passes, acts as a guide tolthe pail in its movements. The pipe D is perforated around its circumference at, a suitable height above its, flange E with a series of holes for the dis-,

charge of the water of condensation, which then passes through the pipe into'any suitable receptacle, or these holes may be on op posite sides of the pipe, in whichpasefthose on each side should beequ l in number," after,

the example of my invention hereinshown,

where four holes are placed on each sidefand opposite to each other to secure an equilibrium of pressure upon the float or pail in its movements. A col1ar,O, is secured within and above the opening in thehottom of the. pail B, and which is oflsuch length as to cover that partof the pipewhich is perforated, thus doing the work of a valve. t i l The operation is as follows: The water of condensation accumulatesin the casing A until its pressure floatsthe'pail B v-When the pail rises above one or more of the holes in the pipe, a discharge of water takes place,which continues until the weight of the pail brings its collar down over the holes again.

It is found in practice that water which is formed from condensation which takes place inthe trap itself will accumulate in thepail until its increasing weight brings the upper edge of the collar below one or more of the holes in the pipe, when its" contents will be discharged down to the level of the heightof'. the

collar So soon as the'ed'uilibriuni' isgrestored between the weightjof the water-W in the pail and the pressure of that iu the casing A and pipe G, the pail will resume its normal position and will close the holes in the pipe D.

It results from this construction and operation that any change in theposition ofthe pail B will uncover one or more of the perforations in the pipe 1). l f the pail is carried downward by the weight of water in itself, then the top of its' coll-arc is brought below the uppermost of said perforations and the Water escapes through the pipe; or if the pail is carried upward, then the lowermost perforations are exposed to the water in the casing.

The cup in the bottom of the pa-il will serve to hold any foreign matter, scales of rust, 850., which -might otherwise reach the pipe and obstructthe discharge.

hat I claim in the construction of steamtraps is 1. The open-mouthed float, with its Villr'fi collar, or their equivalents, in combination
